tending part supporting an integral upturned standard member to which anoperating'lever is pivotally attached. Overlying the laterally extendingplate, just referred to, is .an adjustable gage plate superimposed onwhich is a transverse clamping plate attached by a set screw to thesaidlaterally extending plate or at the junction of the said plate withsaid forwardly'extending part.

" The marking or creasing member consists of a spring sheet metal devicein the form of a loop, the two parts of the said marking or creasingdevice being constructed near their free ends me. well knownmanner forcreas- 1 lngor marking-a fabric. passing between them. The lower armorpart of the said creasing or marking device is arranged to passbeneaththe said clamping plate so that .H. the latter serves to securesaid creasing or" marking device and said gage plate in place. Theoperating lever, which is pivoted to the frame part above referred to,impinges against the upper arm of saidcreasing member and is lifted,after each downward stroke 77, Fig. 1. 7

Referring to the drawings, 12 denotes a presser foot having a shank 13adapted for attachment to the presser bar of a sewing may be adjusted.

imparted thereto by a projection carried by tachment; Fig. 5 is a detailview of the gage plate; Fig. 6 is a detail bottom view of theclampingplate; Fig. 7 is a section on line machine. Formed integral withsaid presser foot, and extending laterally therefrom, is a plate 14having at-its end an integral forwardly extending part 15 integral withwhich is an upwardly extending standard or arm 16 the end of whichisturned forward to form a lug 17 to whichthe operating lever 18ispivoted; These integral parts 12, 13, 14, 15, 16 and 17, constitutetheframe of theattachment. i Overlying' the said laterally extendingplate 14: is a gage plate 19 superimposed on wh ch is a transverseclamping plate 20 whlch is secured to the frame by set screw 21.

The creasing member 22 is in theform of a sprlng sheet metal loop thelower and upper arms of which are constructed, respectively, w1th anupturned lug 22 was groove 23 registering with the said lug 22*. Thiscre asmg member'is of well-known construction and operates in theusualmanner toform'a creaseon a layer of fabric passing over said lug andbeneath said roove. The lower arm of this creasingmem er, which is ofspring? sheet metal, underlies the said clamping plate 20, so that thelatter serves to secure said creasing member as well as said gage platein any positionsto which these parts r r so f The gage plate 19 isprovided near one end with a forward extension 19 having upturned lugs19 at its forward edge and which lugs embrace the lower arm or part ofthe creasing member; and the clamping plate 20 is provided withdownturned lugs 20* which embrace said lower arm of said creasing memberandjwhich also embrace said forwardly extending part, 15 of the frame ofthe at: tachment. V The upturned lugs 19 on the gageplate 19 serve as aguide for the folded edge of, the" fabric being stitched, the adjustmentof the gage plate 19, on which said lugs are formed, determining thewidth ofthe tuck being formed. One of the lugs 19*. is "provided with ahorizontal extension 19 which overlies and smoothes out orpresses downthe folded fabric passing beneath it,

thus doing away with the smoothing out' 10E plates heretofore in use insome tuck-creaslng attachments.

The upward movements of the operating lever 18, under the influence ofthe spring 6 upper arm of the creasing member, are limitediby. a lug24overlying the upper edge of said operating lever and'carlriedby a stopoverlies said forwardly extending frame part and is embraced by saidlugs, a clamping plate overlying said forwardly extending frame part,and also overlying the lower part of said creasing member and said gagelatexa set =screw for said .clam in late plate 24 secured in place by arivet 27'. passing.
